actually there's one more thing i thought of while talking about you
on irc...what lavc options are you using that result in blocking at
q=2? i expect you're using more than just "vqscale=2" by itself, and
there are definitely some options which don't make sense with
constant-q mode and which will severely lower quality. i remember
another user ran into the same thing a while back and it took us a
long time to figure out what the problem was.
